Benchmarks: Full Drive Testing
In our single large file copy test the Crucial MX100 series didn't suffer once it was full – worst case was a loss of just 3 to 4MB/s.
The program test saw a performance drop of exactly 7MB/s on both the 256GB and 512GB models.
On the other hand, our game test saw virtually no difference in performance between an empty MX100 and a full MX100.
CrystalDiskMark shows that sequential write performance goes almost unchanged and these figures are certainly well within our error testing margin.
The random 512K figures are slightly lower but certainly nothing to get alarmed about.
Finally, looking at the 4K-QD32 write performance it's clear that filling the MX100 series has little impact on its performance.
